If you have not purchased a Hadley eyecup yet, you may be interested in the following.
===================
The Lee Shaver is well made and looks like a close copy of the MVA. From the front they almost look identical, but looking closer there are few differences. Both have a rubber ring around the outer edge to help protect the shooter eyes, glasses, stock comb, etc. The outside diameter of the sights are the same. Both have 9 choices of aperture hole sizes. The main differences are the layout of the holes and the size of the holes. The holes in the aperture wheel of the MVA are laid out in reverse order compared to the Shaver, which, unless I'm overlooking something, should make no difference to a shooter. In other words, rotating the MVA aperture wheel clockwise moves from large to smaller holes. Rotating the Shaver clockwise moves from small to larger holes. The holes are of slightly different diameter. The Shaver aperture offers hole diameters from approximately 0.029" to 0.086". The MVA from 0.021" to 0.078". Another difference is the Shaver is stamped L. SHAVER on the front of the sight. The MVA has no markings at all. The Shaver has a matt finish on the front and back. The MVA has a matt finish on the front and a gloss finish on the back. The inside cup surface is a little flatter (less concave) on the Shaver than on the MVA. I'd be hard pressed to pick one over the other. Buffalo Arms gets $65 to $77 for the Shaver depending on the sight thread required. MVA gets $74 to $84 for theirs depending on sight thread required. Maybe some of you with more shooting experience with a Hadley can offer some comments or possibly point out advantages of one over the other.
